The good news? A giant squid invasion could be easily averted with sound waves. The bad news? It turns out that human-created noise pollution might be doing severe damage to the ocean’s cephalopods. (iO9)

@M.P. I refer you to my blog post on the subject, http://operationox.blogspot.com/2011/02/xenomorph-webcomic.html

But good catch. Yes, xenomorph is the term applied to the monsters in "Alien" but as far as I am aware there is no need to limit the term. It basically seems to mean "monster" to me, just in a much more formal usage.

I first saw the term used in English-language signage in Tokyo SOS, and that's partly why I mention it.
